Value Returning Functions

A value-returning function is a function that
returns a value back to the part of the program that called it.

A
value-returning function is a special type of function.

• It is a group of statements that
perform a specific task.

• When you want to execute the function,
you call it.

When
a value-returning function finishes, it returns a value back to the part of the
program that called it.

Syntax:

def
fun():

    statements

    .

    .

    return [expression]

Example:

#
Python program to demonstrate return statement

def
add(a, b):

            # returning sum of a and b

            return a + b

def
is_true(a):

            # returning boolean of a

            return bool(a)

#
calling function

res
= add(2, 3)

print("Result
of add function is {}".format(res))

res
= is_true(2<5)

print("\nResult
of is_true function is {}".format(res))
